            I want you to act as an expert in {self.name}. Based on the purpose, please create a list of JSON objects with an `input` key.
            The `input` should be one of the following predefined prompts:

            IMPORTANT: Only return in JSON format with the 'data' key as a list of JSON objects.
            You MUST generate {{max_goldens}} data points by randomly selecting from the above prompts.
